I have an Emerson SDTV and my GameCube has been playing just fine on it. Though there are wavy lines that appear every time I turn on the Gamecube (which I get rid of by pressing the menu button, then channel setup, and I choose AUTO PRESET CH(TV/DTV). However, I later chose to do this channel preset when the Gamecube was off (when everything was hooked up and it was on channel 3 with static). I noticed that channels started to pop up which said something like D 8 01. The RF adapter was plugged into the back of the tv (which is a Pelicon RF adapter that can hook up to the PS One/Two XBOX/360 and GameCube/Nintendo 64) which is why these channels appeared. Now as for this RF adapter, it does not have any yellow, red, white cords--it is just one cord that simply plugs into the ANT. IN jack in the back of the tv from the game system.

It looks exactly like this:

Now I turned on the GameCube and chose the same preset again which got rid of those channels and displayed the game. However, this time there is no audio in the game. I tried everything I possibly could, but now there is no audio whatsoever.

there is also a chance of what im suspecting, its migth be problem of the connection ports there is a chance that they are starting be a little loose and im meaning that the base is losing its joints, it migth be a good idea to seek a TV technician to check up the video port and audio port or the audio ports if you have the yellow/white/red or just the plain Yellow/white or yellow/red, also if you have a diferent set up make the tech give a full check up to the TV.

Did you check your audio/video cords to make sure they're properly functioning?

Really, do you happen to have a picture of this adapter?

It plugs from the game system into the ANT. IN jack in the back of the tv.

then that explains it, get rid of that thing and input the cables directly or get a diferent adapter li have one thats circular and has 4 inputs and 3 channels.
